Known for her powerful soprano voice, from The Music Man to Funny Girl, Barbara Cook has done it all and more than earned the title of “Broadway legend” along the way. Now 85, Cook recently returned to Carnegie Hall—the site of her most famous live recording—and proved that her strength is undiminished; as the New York Times put it the next day, “Ms. Cook has reached the point in her career where she has nothing left to prove.” Catch Cook in a special post—Valentine’s Day concert on Saturday, Feb. 16, at the Green Music Center. 1801 E. Cotati Ave., Rohnert Park. $35—$90. 8pm. 866.955.6040.
